Other claims from this paper (7)
- Intervention effect Drought decreased osmotic potential at full turgor in rose leaves, by 0.42, 0.36 and 0.23 MPa at 100%, 70% and 30% irradiance.
- Observation Plants under 100% and 70% irradiance showed similar osmotic adjustment to drought.
- Intervention effect Under well-watered conditions, plants at 30% irradiance had higher osmotic potential at full turgor than at the other two irradiance levels.
- Intervention effect Plants at 30% irradiance showed only 55% as much osmotic adjustment to drought.
- Intervention effect Drought increased the elastic modulus of rose leaves in each irradiance treatment.
- Intervention effect Turgor pressure was higher across a range of relative water contents at 100% and 70% irradiance than at 30% irradiance.
- Intervention effect Heavy but not mild shading inhibited osmotic and turgor adjustment in rose leaves during drought.
